I was in Paris back in Feb and (although I studied for 5 years in school) I have no french. If you get a metro map you will find out which station you need to get to really easily - all of the metro stations I was in had a teller at the ticket booth and although some of them have no english if you point at the map they will know were you are going.
I'm heading back in 5 days and I think the metro is one of the best things about Paris because its so big - you should really take advantage of it!
From the airports you ve mentioned the harder one is from Beauvais. It is expensive, 13 euros to Paris, takes 1 hr in a shitty bus. Then from the last stop of that bus , which is on the westbound city limits of paris (Porte Maillot), you take the metro.
from CDG, you take RER B(suburb train) to Gare du Nord, then metro line 5, change at republique to line 8. your place is actually very close to Gare du Nord, 5 stops, so I advise you to take a cab from Gare du Nord, will cost you nothing.
Ticket machines, all have the option of english right now. Metro system of Paris is for me the easiest to cope with in Europe, taking into account its hundreds of stations and the covarage.
hope this helps...
